Marien started to write an extension called AnonymousReferer.

This extension aims at deleting the http referrer when the FreshRSS user click on a post to see it on the original website. The http referrer is deleted by the use of an anonymous redirection service known as anonym.to, deleting the referrer is as simple as adding the http://anonym.to/? prefix to each link. The extension is available for download.

Unfortunately, the extension is not as complete as the original extension that came from KrissFeed. The extension only deletes the referrer for the link to the original post while ignoring all links inside the post.

The extension from KrissFeed has the following options :

• leave the configuration field empty to not modify the behaviour (leave links as is)
• fill-in the field with http://anonym.to/? to use the anonym.to service (what is partially done by the actual extension)
• fill-in the url of another service which API si similar (in case anonym.to would be blacklisted by your ISP)
• fill-in noreferrer to use the html5 property

The KrissFeed extension does only change links (but all links) and not other media files which are then downloaded directly (images and others).
